The problem here is that people don't have a good system for solid trading. They make a decision and then they move all in and all out of a market instantly. This kind of emotional trading is just bad practice and will always turn out unfavorable on average.

Personally I'm working on a 20-point system that will help myself and others move in and out of the markets with much more grace. Each "point" is simply 5% of the funds you're gambling with, and there are rules for how many points you should move in or out of the market at any given time. Honestly I think a system like this could help a lot of ppl.
